IMPROVEMENT IN SHUTTLE FOR LOOIMS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom 'it may concern:

Bc it known that I, RUDOLF WEBENDRFER, of New York city, in the countyand State of New York, have invented a new and useful Improvement inLooms; and I do hereby declare that the following is a full, clear, andexact description thereof, which will enable others skilled in the artto make and use the same, reference being had to the accompanying,rdrawings, forming part of this specification.

Figure 1 represents a front view cfa loom provided with my improvements.

Figure 2 is apian or top view of the shuttle:

Figure 3 is a longitudinal section ofthe same.

Figure 4 is a vertical transverse section of the same. Similar lettersof reference indicate corresponding parts.

This invention has for its object to construct a positive-motion loom,in which the shuttle is not pushed ahead, and, at the same time, Bto doaway with the blelt, chain, or other constant connection with the shutte. The invention consists in confining, within the shuttlc, themotive-power that propels the same. The loom will thereby combine theadvantage of an unobstructed shuttle with that which is operated bypositive motion, and will work accurately and in a reliable manner,without injury to the threads through which the shuttle passes, northose whichit carries.

y The motive-power ofthe shuttle is obtained from two springs insertedin the shuttle, and wound up alternately at the ends of the raceway topropel it in 'lhewinding-up apparatus is attached to the loom, and isput in action at the end of every stroke.

A, in the drawing,'represents the shuttle of suitable form. It contains,between or outside of its sides, wheels a a, on which it rolls. The-sewheels, or, at least, one of them, should be adapted to receive thepropelling-power.

lhe axle of one of the wheelsc is, therefore, by toothed wheels b b, orbybelt or otherwise, connected with a shaft, B, which is hungtransversely in the shuttle.

Around the shaft B are fitted two coiled springs, O D, side by side,they being coiled in opposite directions. lheir inner ends are bothsecured to the shaft, while their outer ends are secured to the rims oftwo hollow The drums are hung loose on the shaft B, and haveratchet-teeth, in opposite directions, on their outer faces.

lVhen one .of the ratchet-drums is heldsecnre by a pawl, and its springis wound up, the spring will unwind from the inner end, and willthere-by revolve the shaft, which, by its gearing-connection, willrevolve the wheel a, and thereby propel the shuttle.

Asthe springs are set in opposite directions, the one will revolve theshaft B in one direction, while the other will reverse the motion, andconsequently,

also, the motion of the shuttle will be reversed, as the' springs arebrought into action alternately.

The change of motion is yproduced by two pawls, c and d, which areaffixed to a rock-shaft, 0,'that is hung to carry the pawl c off thedrum E, and, at the same time, to loch the pawl d into the drum F..

The spring D is then wound up, and will propel the shuttle in theopposite direction, until the arm f is again struck, to throw the pawl cinto, and d out of gear. l i

'lhe winding up is produced by suitable parts of theloom. lhat shown inthe drawing represents frictionwheels g g, propelled by wheels It, thatvare hung in fixed pivots, while the wheels glare hung on levers i,pivoted hy the axles of h.

lVhen the shuttle arrives at one end of its stroke,

the lever 'i at that end is elevated by a spring, or its may be variedat will; neither do I claim the par-r ticulararrangement of the wheelsa, and of their connection with the propelling-mechanism.

If desired, the two springs and their drums maybe. arranged uponseparate shafts, in which two rods, for setting the pawls, must be used.

Havin g 4thus describedvmy invention,

I claim as new, and desire to secure by Letters Patent- Y 1.. Theshuttle for looms, .containing two springs, which propel it in oppositedirections, asset forth.

2. The drums E F, containing theV springs O D, for propelling a shuttle,and held'v in place by pawls c d, when the springsb are to act assetforth. t The pawls c d, arranged to lock the drums E F in a shuttle, andacted upon by one or more arms, f, at the end of each stroke, as setforth.` 4. rI he wheels a a, arranged on a shuttle, and revolved inopposite directions by thcactio'n of springs,

substantially as specified,

The above specification ofi my invention signed by me, this 16th day ofNovember, 1869.
